Zipper layer method

Abstract

Based on the buffer layer method, a new method called zipper layer method was developed. This method maintains the capability of the buffer layer which can link two topologically different multi-block structured meshes together, while significantly improving the robustness. This method can both locally and globally connect two dissimilar structured meshes with tetrahedrons and pyramids to form a conformal mesh. The NASA Rotor 37 and an open rotor are used as test cases here to generate the zipper layer meshes. The numerical results on these zipper layer meshes compared well with those on the multi-block structured meshes.
